BARREL-MAKING MACHINE.

Application filed September 12, 1921. Serial No. 500,142.

The invention relates to barrel-making machinery and more particularlyto a machine for heading up wooden barrels and for removing form ortrussrings used in the manufacture of the barrel.

In the making up of barrels, particularly heavy barrels for containingliquids, it is customary to assemble the staves, in the earlier processof manufacture and seasoning, within heavy iron or steel truss rings orhoops including a hoop at each end of the barrel and a pair of bilgehoops around the center portion of the barrel. In the final process ofmanufacture it becomes necessary 'to re move these temporary form ringsand substitute therefor the ordinary barrl hoops, and by reason of thetightness required in the joints between the staves and the stressoccurring in the bending of the latter, the truss rings are driven onwith great force and are difficultto remove for the substitution of theordinary hoops.

It is an object of this invention to provide a machine by which the endportions of the staves about the compressed sufficiently to permit theready removal of the truss rings and their replacement by permanenthoops.

It is a further object to provide for the simultaneous dislodgment fromthe center portion of the barrel of the bilge truss rings.

A further object is to so construct the operating parts as to permit theemplacement and removal of thebarrels from the machine with greatfacility and economy of time and effort.

A further object is to provide a machine for the purposes describedwhich 1s of a very simple and durable construction, and adjust ablyadapted to operate upon barrels of vari" ous sizes with equal facility.I

Other objects and advantages Wlll be apparent in the followingdescrlption of a preferred embodiment of my invention which I a haveillustrated in the accompanying drawings.

Referring to the drawings, Figure 1 represents a plan view of thecomplete machine. Fig. 2 represents a rear elevation of the machine.Fig. 3 represents a side elevation and Fig. 4 a fragmentary sectionalview of the clutch and driving mechanism. v

The frame of the machine may be variously constructed, but in my'preferred embodiment head of the barrel may be 1 I have illustrated amain frame having a base 1 constructed with lateral upright portions 2upon which latter are mounted a pair of upright standards 8. The upperends of the standards are formed with L-shaped rear ward extensions 4 inwhich latter is horizontally'pivoted at each side a head frame 5. Thepivots are located in the head frame structure a substantialdistancerearwardlv of the center portion thereof, which permits thefront portion of the head to be swun upwardly. When in horizontalposition th: head frame 5 rests forwardly ofits pivots upon the upperends of the standards?) as at 6. i Located centrally betweenthe uprightpor tions 2 of the base is a horizontal table 7 which may be mountedwith any suitable means for raising and lowering the level of the table,as by hand screws 8. The table 7 18 adapted to receive a barrel standingon end and extending upwardly through the head rame 5 when the latter isin lowered positron, the upper end of the barrel bein in position to begrasped by clampin devices hereinafter described. b

The swinging head frame 5 carries on' its upper surface a plurality'ofclampingqjaws,

of which I have illustrated herein the three aws 9, 10 andll mounted inways on the head frame and arranged to slide radially to and from thecenter of the opening in the head whereln the barrel is received. Theinner faces 12 of the clamping jaws are formed with circular peripheriesof a suitable'radius to effect substantially continuous 'fcontact withthe barrel being clamped thereby.

Tn my present embodiment one ofthe jaws 9 is adapted to be manuallymoved on its radial ways by means of-an eccentric 'pin 13 having itslower portion .14 journaled in the head frame and an eccentricportion 15operatively extending through a transverse slot bearing 16 in the jaw 9.Thejaw' 9 thusmay be withdrawn to clear the opening in the head framewhen placing a barrel to be operated upon. A handlef 16 is provided bywhich to rotate the pin.

The other two jaws 10 and 11 are also radially slidable in similar ways17 formed in the upper surface of the head frame 5, and

are positioned with respect to each other and,

the jaw 9 so that their inner peripheries when normally closed. ointlydescribe circle cf Inn till

cross-head is connected at each side with the respective outer ends ofthe rockers 18 by means of longitudinally adjustable con necting rods22, the rod connections both with the cross-head and with the. rockersbeing pivoted. The connecting rods 22 are so arranged in relativeposition that by the inward movement of the cross-head 20 a powerfultoggle action is produced which operates the rockers to force the jaws10 and 11 inwardly upon the barrel end supported within the head frame 5and rigidly held by the third jaw 9.

For the operation of the toggle mechanism I have provided powertransmission means comprising a pair of inter-geared driven shafts 23and 24 having their. bearings in the lateral upright members 2 of thebase, with their ends extending outwardly therefrom, and one of whichcarries a suitable cam mechanism for the operation of a rocking leverwhich actuates the cross-head 20. More particularly described asillustrated in my preand drives a gear 26 fixed on the outer end of theother shaft 23 which'latter carries .at its opposite outer end a fixedpinion 27 meshing with a gear 28 fixed on the shaft 24.

The arrangement of gears and shafts here described is to providesuflicient gear reduction in most compact form to give the desired powerfor the eflicient operation of the jaw operating mechanism. The shaft 24is further supported by intermediate bearings provided in a pair ofupright bearing supports 29 formed integrally with the base 1.

Fixed centrally upon the shaft 24 between the bearing supports 29 is acam member 30 of which the operative periphery is in contact with aroller 31 carried by an upright rocker arm 32 centrally pivoted upon arocker shaft 33 carried in bearings 34 formed in upward extensions ofthe two bearing supports 29. The upper end of the rocker arm 32 extendsrearwardly and in operative contact with the cross-head 20 of the togglemechanism. The arrangement of the rocker arm and cam is such that witheach revolution of the cam the rocker arm is actuated to force thecrosshead 20 inwardly to close the clamping jaws.

Operative contact between the cross-head and the upper end of the rockerarm may be accomplished through a cushioned driving head 35 which ispositioned in a recess 36 in the end of the rocker arm and which lattercarries therein a compression spring 37 adapted to cushion the force ofthe inward. movement of the rocker arm. A stem 38 upon the head 35extending through the rear wall of the recess, is engaged by a retainingnut 39. The contacting faces of the driving head 35 and the cross-head20 are arranged so that the head frame 5 may be swung 011 its pivotswhereby the rearward end of the head frame carrying the toggle mechanismis dropped downwardly out of contact with the rocker arm.

The mechanism for removing the temporary bilge hoops from the barrelwhenp'ositioned on the platform or table 7, includes a pair of slideways4O vertically positioned and preferably formed on the inner surfaces ofthe inwardly projecting portions 41 of the two standards 3. Operatingtherein respectively are a pair of slides 42 each carrying at its lowerend a pair of pivoted links 43 connected to the outer end of one of apair of horizontal rocker arms 44 centrally bearing and supported on theshaft 23.

rocker arms 44 extend rearwardly carrying at I their respective rearextremities rollers 45 having operative contact with the peripheries ofa pair of cam members 46 fixed on the shaft 24 and which are arranged toactuate the rocker arms and vertically reciprocate the slides 42 intheir respective. ways.

On the inner faces of the slides 4 are mounted in each instance avbracket 47 suitably secured for vertical adjustment of position upon theface of the slides as by means of bolts 48 and a series of bolt holes49. Pivoted to each of the brackets 47 is a depending dog 50 normallyactuated to swing inwardly by means of a compression spring 51. carriedby a bolt 52 mounted in the bracket and far ranged to effect compressionof the spring by the outward swing of the dog. The lower ends of thedogs are eachformed with a notch or shoulder 53 suitably arranged toengage a bilge truss ring or temporary hoop carried by a barrel beingoperated on as illustrated at 54, and with the downward movement of theslide to force the bilge ring from the barrel.

The several cam. members operating the clamping jaws and the truss ringremoving dogs, are preferably in such relation that the downwardmovement of the dogs occurs simultaneously with the inward movement ofthe jaws, and likewise with the opening of the jaws, the dogs arereturned to their initial position.

The

lil

In order to control the operation ofrthe V clamping jaws and ringremoving mechamsm, I have provided a clutch mechanism all whichpreferably comprises the arrangement illustrated in Fig. 4., The loosepinion is formed with an integral sleeve extending outwardly along theshaft 24 and abutting the inner surface of the hub of a pulley 56, thelatter also being mounted for free rota tion upon the shaft 24. Thepinion and pulley are secured in longitudinal position by means of acollar 57 suitably fastened at the outer end of the shaft 24, the innersurface of the pinion being confined against opposite movement by theouter faceof the adjacent shaft bearing. The inner face of the pulley 56is provided with a cone shaped re-- cess 58 with which is associated acone clutch 59 of well known construction, which is carriedby a sleeve60 slidably overlying and splined upon the inner sleeve 55. The clutchand its carrying sleeve may be moved longitudinally into drivingengagement with the pulley by means of a shifting bar 61 having suitablemeans to emb ace the leg of the operator standing before the machine,preferably constructed as illustrated at 62, and adapted to operate thelever 63 pivoted on the main frame. The latter operates through thepivot pin 6a a shifting lever 65 formed with a yoke embracing thesliding bar 66 which carries at its outer end a yoked element 67carrying pins suitably positioned to enter in rotative engagement anannular slot 68 formed in the clutch sleeveGO. By'a movement of theoperators leg the clutch mechanism is thus conveniently thrown into andout of engagement.

In operation, the head frame 5 is thrown upwardly, a barrel is placed onthe table 7 in upright position as illustrated in Fig. 2, and

the table adjusted to the desired height,

whereupon the head frame is swung downwardly with the barrel extendingthrough the central orifice of the frame with the end truss ring clearof the clamping jaws. The machine is then put in operation until thejaws are securely clamped about the upper end of the barrel whereuponthe clutch is released and the end truss ring removed from the barrelwhile the staves are so compressed. A permanent hoop may then be placedon the barrel and the machine again put in operation to complete therevolution of the cams and release the clamping jaws. Simultaneouslywith the closing of the jaws the lower bilge ring has been struck fromthe barrel.

It will now be apparent that I have provided a readily operable andefficient means for replacing the truss rings with permanent hoops withconvenience and economy. While I have illustrated and described indetail the preferred embodiment of my invention, it should be understoodthat in the interpretation of the appended claims it is not intendedthat they are to be limited to the precise construction and arrangementtherein contained as many variations and modifications will naturallyoccur to those skilled in the art.
